The decisive criterion for all Polyester applications is that the use of repelletised material should not affect either extrusion or any following process, nor should it jeopardize the quality of the end product. The Starlinger recoSTAR product line offers the ideal solution for PET and PES recycling, as it fulfils both conditions with optimal pre-drying of the PET, ideal screw design, inline quality control, and optional solid stating.

'''recoSTAR PET recycling lines'''


The '''recoSTAR PET''' series  is designed for the recycling of post-consumer bottle flakes after the washing process as well as for the in-house recycling of PET flakes from bottles, preforms, strapping bands and sheets. The end product is always melt-filtrated, uniform granulate that can be used for a wide range of applications. (Brochure)

Various proofs for food contact safety such as the US (FDA Letter of Non-Objection), Canadian, Austrian and French as well as ILSI and German BfR approvals have been achieved. In addition, the conformity to EFSA and brand owner approvals underlines the superior quality of rPET produced on Starlinger recycling lines.

'''recoSTAR PET extrusion (flakes to pellets)'''


PET flakes are heated and dried in a two-stage process by means of hot air and dry air, or under vacuum. The special design of the dryer outlet results in center flow prevention, consistent residence time and FIFO processing. This ensures decontamination for food contact applications and ideal preparation for the extrusion process with maintained IV level ('''recoSTAR PET FG''') or with IV increase ('''recoSTAR PET FG+''').

'''recoSTAR PET with Starlinger iV+ technology (flakes to SSP pellets)'''
=== '''recoSTAR PET with Starlinger iV+ technology (flakes to SSP pellets)''' ===


The Starlinger iV+ recycling process for PET food contact applications consists of two main steps: the continuous extrusion process, and the semi-continuous solid-stating process either before or after the extrusion step ('''recoSTAR PET iV+'''). It turns post-consumer PET flakes into pellets that meet the highest requirements.

With '''recoSTAR PET iV+ Superior''' the combined decontamination steps of both the flakes in the vacuum dryer upstream of the extruder (FG+) and the pellets in the SSP reactor downstream of the extruder (iV+) result in the highest possible quality of pellets. This superior decontamination process reduces acetaldehyde (AA) and volatile contamination (VOC) to a minimum.
